Maternal autoantibody related (MAR) autism goes mainstream

"MARAbio Launches First-Ever Blood Test For Maternal Autoantibody Related Autism" https://www.marabio.com/test-launch

Woah. 

Just when you thought 2025 couldn't bring anything else to the world of the autisms (plural), a press release which was kinda expected but is now an actuality.

MAR autism - maternal autoantibody related autism - has been on the research menu for a while. Quite a few scientific papers have found it and indeed, found the specific autoantibodies (to foetal tissue) that seem to be pathogenic for risk of this type of autism. And it's not just testing either, as some science has talked about the ways-and-means to 'avert' the effects of those antibodies too and impact on offspring autism risk. This has been years in the making. 

"Commenting on the potential impact of this launch for providers and families, noted clinician and autism researcher Richard E. Frye, MD, PhD, said, "With MARAbio's test now available, particularly for those families already touched by autism, we now have access to meaningful insights into this particular and prevalent cause of autism, including the likelihood of MARA in future children. It's an exciting advancement that brings science and compassionate healthcare together in a truly impactful way."

It should perhaps be noted that the research into other types of autoantibodies - folate receptor autoantibodies - by Dr Frye and others has also been an achievement unlocked in 2025. Indeed, both these streams of research and now clinical practice, whilst so far distinct, point to a pivotal role for immune functions and their effects across quite a few autisms. And that should provide some important clues for future work on 'how and 'why' and what to do about it.

And yet more evidence for those plural autisms which is music to my research ears...
